WebDec 30, 2024 · Nowadays, geopolymer binder is attracting a growing interest as an alternative to cement for concrete production. It has been shown that geopolymer concrete exhibits compressive strength which is comparable with that of cement-based (Jo et al. 2016; Pasupathy et al. 2024; Nazari et al. 2024). Fly ash has been widely used as the … WebJan 1, 2024 · Fly ash is a finely divided d residue resulting from the combustion of pulverized coal and transported by the flue of boilers that carries gaseous combustion away from the point of combustion.... binge eating disorder statpearls

WebTo solve the issues of insufficient early strength of cement stabilized soil and high resource cost, high reduction cost, and high environmental cost induced by the application of cement, the slag and fly ash-based geopolymer was adopted as the stabilizer to treat riverside soft soil. This study mainly investigated the effects of stabilizer content, slag-to-fly ash ratio, … WebApr 11, 2024 · Further, Hardjito et al. (2008) tested both class C and class F fly ash by increasing the alkaline activator to fly ash ratio and observed an increment in the compressive strength, in which 0.40 of optimum activator to fly ash ratio yielded the highest compressive strength (refer to Fig. 11). WebMay 1, 2016 · Physical and chemical properties influencing the reactivity of fly ash (FA) were assessed. • Optimum activator dosages were identified giving compressive strength of 70 MPa.. FA samples cured at 70 °C were considerably stronger than samples cured at 50 °C.. Partial FA replacement with ggbs leads to increases in the compressive strength. binge eating disorder specialist
